    Abstract: A fragment having -300 base pairs was obtained from a plasmid, PILM 7, cut by XbaI and PvuII. On the other hand, a fragment having - 4,500 base pairs was obtained from aplasmid, pNK2, treated with XbaI and PvuII. Both of the fragments were ligated and inserted into a proper strain to get pNKM 21. pNKM 21 was inserted into M 5248 strain to get KCTC 8258 P strain followed by culturing it to give a interleukin-2 contg. serine at 125-position instead of cystein.

    Abstract translation: 从由XbaI和PvuII切割的质粒PILM7获得具有-300个碱基对的片段。 另一方面,从用XbaI和PvuII处理的质粒pNK2获得具有-4,500个碱基对的片段。 将两个片段连接并插入适当的菌株中以获得pNKM21。将pNKM 21插入M 5248菌株中以获得KCTC 8258P菌株,然后培养以产生白细胞介素-2对照。 丝氨酸位于125位,而不是半胱氨酸。
